The Mythbusters-themed episode, which is directed by Chad Lowe, focuses on the death of a TV host who debunks urban legends like Yeti and Bigfoot. Brennan (Emily Deschanel) is a firm nonbeliever in such unsubstantiated stories, and Booth (David Boreanaz) disagrees with his partner’s hyper-rational stance. In fact, his exact words are, “You haven’t seen the backside of the moon, but you believe in it.”

Leave it to Brennan (or was it John’s handiwork?) to come back with, “I was trying to think of an amusing quip about the backside of your moon.”

These two may butt heads on occasion, but at least they can laugh about it.
